Abstract

Inhibition hydrolysis of carbohydrate by mulberry leaves extractABSTRACT. Mulberry leaves has a great potential as animal feeds because of its high nutrient content, but has deoxynojirimycin (DNJ) active matter. It is potential to inhibit carbohydrate hydrolysis process, come to monosaccharides. The objective of this experiment is to study the inhibiting ability of mulberry leave extract in carbohydrate hydrolysis process. The kinds of carbohydrates were using glucose, maltose, sucrose and starch. This experiment used twenty four of 60 days old male mice (Mus musculus). Diet and water were given ad libitum. Treatment were allocated ina factorial completely randomized design with three replications and two factors containing of completely mulberry leaves extract and variance of carbohydrates. Variable observed were feed consumtion, feed digestibility, body weight gain and blood glucose. The data were analyzed with univariate analysis of variance. The result showed that inclusion of mulberry leaves extract had decrease body weight (P 0,05) and reduce blood glucose (P 0,05).

Abstract

Urea Mineral Molases Liquid (UMML) dan biomassa murbei dapat menjadi prekursor biofermentasi dalam sistem rumen. UMML dapat menyediakan nitrogen lepas lambat, mineral larut air dan readily available carbohydrate (RAC), sedangkan biomassa murbei dapat menyediakan RAC, asam amino bercabang, mineral dan vitamin.  Formula UMML adalah larutan yang tercampur dari bahan-bahan yang terdiri atas Urea-kalsium (Ca(urea)4Cl2), molases dan larutan fosfat (fosfat dilarutkan dengan asam organik). Diperlukan jumlah UMML yang tepat dalam ransum sehingga ransum menjadi efisien. Penelitian ini menguji tingkat penggunaan UMML yang efektif mendukung biofermentasi bahan pakan campuran jerami padi dan biomassa daun murbei dalam sistem rumen. Ransum uji terdiri atas jerami padi dan biomassa murbei dengan perbandingan 70:30, yang diaplikasikan tiga perlakuan yakni tanpa penambahan UMML serta penambahan UMML sebanyak 10% dan 20% (v/w). Pengujian dilakukan pada  rumen in vitro. Peubah yang diamati adalah nilai pH, konsentrasi amonia dan VFA,  produksi gas dan tingkat degradasi bahan kering ransum.  Hasil penelitian menunjukkan bahwa penambahan UMML yang terbaik pada fermentasi campuran jerami padi dan biomassa murbei adalah sebesar 10%.

Abstract

Compound of 1- deoxynojirimycin (DNJ) in the mulberry leave extract (MLE) potentially hamper the hydrolysis process of various carbohydrates. This experiment aimed to study dynamic concentration of reductive sugar resulted from the hydrolysis of various carbohydrates by raw enzymes of the rumen liquid, with or without the addition of mulberry leave extract containing 1-deoxynojirimycin. Materials tested are maltose, sucrose, starch and cellulose.  The result of the experiment showed that the addition of mulberry leave extract on the media with the substrate of maltose hampered the activity of maltase.  It was concluded that MLE containing DNJ can be used as an agent of slow release mechanism of non-structural carbohydrates, especially maltose, in the rumen system.

Abstract

Mulberry biomass has potential ruminant feed quality due to its potential for the production and content of nutrients, but its utilization as feed is still diffcult to fnd. The residual of agriculture also has considerable potential as a source of ruminant feed. The combination of agriculture byproducts such as corn straw and the mulberry biomass into a complete ration in form of wafer is an effective alternative for producing complete feed. The ration was formulated into a complete ration in the form of wafers (wafer complete feed) which was characterized by a quality suffcient nutrient content and a compact form of the product. To complement the availability of nutrients, improve both physical quality and palatability, the complete feed wafer was formulated using such raw materials as corn straw, mulberry biomass, concentrate, and molasses. This purpose of this study was to evaluate the physical properties of wafer complete feed. The study was carried out according to completely randomized design (CRD) consisted of six treatments and four replications for each treatment. The amount of complete feed formulated for each treatment was 1000 g dry matter basis with diameter of 21 cm. The physical properties of complete feed formula were evaluated based on the density value, water absorption, and rupture test (crushing test). The best result in formulating complete feed wafer was obtained by using a combination of 5 - 10 % molasses with 25 - 30% mulberry biomass.

Abstract

The purpose of this experiment was to examine the effects of mulberry leave meal to substitute concentrate in rice straw based ration on blood profiles of Ongole crossbreed cattle. This experiment was carried out according to completely randomized design consisted of 3 treatments and 4 replications. The treatments were P1 (50% rice straw + 50% concentrate), P2 (50% rice straw + 25% concentrate + 25% mulberry leave meal), and P3 (50% rice straw + 50% mulberry leave meal). Parameters measured were blood profiles, i.e. blood glucose, blood cholesterol and blood HDL. The results showed that substitution of concentrate with mulberry leave meal significantly reduced (P<0.05) blood glucose and increased blood cholesterol and HDL. It is concluded that mulberry leave meal can be used to substitute concentrate and give a positive effect on glucose, cholesterol,and HDL contents of blood.

Abstract

Coastal communities play an important role in marine and fisheries development, as well as forming a culture in coastal areas. The socio-economic life of coastal communities in Kolakaasi Sub-District of Kolaka District is far from prosperous as the data obtained from Badan Pusat Statistik  of Kolaka (2015), the number of poor population in Kolaka reached 27,210 with the percentage of 14.68%. Partners in this IbM activity are teenagers who drop out of school environments and groups of housewives living in coastal areas. The problem of partners in the activities of IbM is the number of teenagers dropping out of school in the partner environment due to the low level of welfare of coastal communities so that the average level of the highest education is junior high school where the young women have to help the family economy by working as laborers in traditional markets of Kolaka or only help parents at home while the men work at sea. Fishing is highly dependence to the nature, so that if the weather is bad then the fishermen cannot gain  income. IbM-Integrated Farm by making "POC-FISH" is the manufacture of liquid organic fertilizer that combines agricultural activities with fisheries. POC-FISH is mad of small fish, commonly called lure fish (teri) by Kolaka community. This type of fish is abundant in Kolaka and sold cheaply (R.p 5,000/Kg). The purpose of this IbM activity was the empowerment of coastal communities through the transfer of science and technology by utilizing local potentials so that the partners involved can begin to be productive and economically independent by conducting business on a household scale. The method of making POC - FISH will be carried out simply so that technology transfer can be easily understood by partners. The process of transfer of science and technology was carried out with the pattern of 1) the education of the partner group on the importance of technology adoption by utilizing the potential and local wisdom that will be able to produce a product with higher economic/selling value 2) POC-FISH making training 3) mentoring partner group in marketing 4) monitoring and evaluation. The outgoing plan of this IbM activity is the publication of the ISSN national journal published in 2017 and POC-FISH Products

Abstract

People of Kolaka accustomed to using coconuts as well be used as a food supplement or a mixture of additives in processed foods, cakes and other confectionary. Therefore utilizing coconut pulp as feed fish and poultry should be made to minimize the potential for household waste. Feed from coconut pulp is a transfer of science and technology to the people who are expected to help poor people to be productive. Fermentation is one method to process coconut pulp into feed ingredients. The fermentation process is done by using spores of Aspergillus niger. The fermentation process is done in stages, by aerobic fermentation followed by anaerobic fermentation (enzymatic process). In short the process of making feed "PA-BIO" from coconut pulp is: Dregs of coconuts added water, stirred and steamed. Cooled and then stirred together with a mixture of minerals, Aspergillus niger spores are added and stirred again until evenly distributed. The mixture was then fermented aerobically and unaerobically. Dregs fermented and then dried and packaged for later in packing. Based on the results of research that the utilization of coconut dregs as cattle feed and fish is potential. Miskiyah et al. (2006), increase protein content after fermentation of coconut pulp 11.35% to 26.09%, or by 130% and decreased fat content of 11.39%. The results also showed that the feed produced quite safe for livestock, namely the aflatoxin content <20 ppb. Feed from coconut pulp is also good for fish farming. Goenarso et al. (2002) on tilapia (Oreochromis niloticus L.), the faster fish growth with increasing the feed protein content of 25%, 30%, 35%, 40% and 45%.
